I have removed my airbox and the rubber boot immediately behind all four carbs for cleaning and some paint. After 45 years the factory sealant for the outlet boot of the airbox and the inlet rubber boot have dried up and lost any semblance of airtightness.
What is the recommended sealant to get these airtight again? I'm sure I need to use something that won't have a negative affect on the rubber.
Thank you for your time and help.
